Three crude oil and three extract samples collected from three source rocks namely Bahariya, Alam El Bueib, and Khatatba Formations from the Egyptian productive wells namely: Bed 2-1, Bed-2, and AG-1 oil fields. The oils were analyzed geochemically, including sulfur content and API gravity. Capillary gas chromatographic analysis was applied on each saturated hydrocarbons from oils and extracts to assess the correlation between the crude oils and the potential source rocks in order to confirm the indigenous sources for the petroleum generation of studied oil fields. The results show that the oil samples are originated mainly from marine organic sources deposited in reducing environment. By correlation between the source rocks and crude oils, we show that there is a good correlation between the extracts of Alam El Bueib and Khatatba source rocks with crude oils; while the extracts of Bahariya source rock show no correlation with the studied samples. These evidences indicate that Alam El Bueib and Khatatba source rocks seem to act as a source and reservoirs for oil generation in the studied oil fields.
